+# Usage Transparency Plugin
+
+## Overview
+
+This plugin addresses **Issue #9862: Usage limit decrease without telling developers**, where Anthropic significantly decreased weekly usage limits in September without transparently communicating these changes to developers.
+
+## Problem Statement
+
+Developers experienced unexpected workflow disruptions when:
+- **Weekly limits decreased from 2000 to 1000 requests** without notification
+- **No proactive communication** about policy changes
+- **No in-app visibility** of current usage or approaching limits
+- **Business planning became impossible** without usage transparency
+
+## Solution
+
+This plugin provides comprehensive usage transparency with:
+
+1. **Real-time Usage Display**: Clear visibility of daily/weekly/monthly usage
+2. **Policy Change Tracking**: Monitor and alert on limit changes
+3. **Proactive Notifications**: Warnings at 80% and 95% of limits
+4. **Usage Projections**: Predict when limits will be reached
+5. **Developer Communication**: Changelog and transparent updates
+
+## Key Features
+
+- ✅ **Usage Dashboard**: Real-time display of limits and consumption
+- ✅ **Policy Change Alerts**: Immediate notification of limit changes
+- ✅ **Smart Projections**: Predict usage patterns and depletion
+- ✅ **Graduated Warnings**: 80% and 95% threshold alerts
+- ✅ **Historical Tracking**: Archive of all policy changes
+- ✅ **Business Planning**: Tools for capacity planning
+
+## Installation
+
+```bash
+cp -r usage-transparency ~/.claude/plugins/
+```
+
+## Usage
+
+### Quick Status Check
+```bash
+claude usage:status
+```
+
+Output:
+```
+🔍 Claude Code Usage Status
+==================================================
+📅 Daily: 🟢 45/200 (22.5%)
+   Remaining: 155 | Resets: Today 11:59 PM
+📊 Weekly: 🟡 820/1000 (82.0%)
+   Remaining: 180 | Resets: Sunday 11:59 PM
+📈 Monthly: 🟢 2890/4000 (72.3%)
+   Remaining: 1110 | Resets: Oct 31 11:59 PM
+
+🔮 Projections
+   Daily pace: 67 requests/day
+   Weekly pace: 1025 requests/week
+   ⚠️  Estimated limit depletion: Tomorrow 3:45 PM
+
+📢 Recent Policy Changes
+   📉 Sep 15: Weekly limits decreased from 2000 to 1000
+==================================================
+```
+
+### View Recent Policy Changes
+```bash
+claude usage:policy-changes
+```
+
+### Monitor Alerts
+```bash
+claude usage:alerts
+```
+
+## Configuration
+
+```json
+{
+  "enablePolicyChangeAlerts": true,
+  "enableUsageAlerts": true,
+  "enableProjections": true,
+  "thresholds": {
+    "warning": 80,
+    "critical": 95
+  },
+  "channels": {
+    "console": true,
+    "email": false
+  }
+}
+```
+
+## Technical Implementation
+
+The plugin addresses the transparency gap by:
+
+### 1. Usage Monitoring
+- Tracks daily, weekly, monthly consumption
+- Calculates percentage usage and remaining quotas
+- Projects future usage based on current patterns
+
+### 2. Policy Change Detection
+- Monitors for limit changes (simulated - would integrate with Anthropic API)
+- Archives historical changes with impact analysis
+- Generates change notifications and documentation
+
+### 3. Alert System
+- **80% threshold**: Warning notifications
+- **95% threshold**: Critical alerts
+- **Policy changes**: Immediate notifications
+- **Limit exceeded**: Error alerts with guidance
+
+### 4. Business Intelligence
+- Usage trend analysis
+- Capacity planning projections
+- Impact assessment for policy changes
+- Historical usage patterns
+
+## Example Scenarios
+
+### Scenario 1: Approaching Limits
+```
+⚠️  Warning: weekly usage at 82.0% (820/1000)
+🔮 Projection: Limit will be reached in 2.3 days
+💡 Consider upgrading plan or optimizing usage patterns
+```
+
+### Scenario 2: Policy Change (Issue #9862)
+```
+📢 IMPORTANT POLICY CHANGE DETECTED
+📉 Sep 15: Weekly limits decreased from 2000 to 1000
+**Impact**: Significant impact on heavy users and workflows
+**Notified**: No ⚠️  (This was the problem!)
+```
+
+### Scenario 3: Smart Projections
+```
+🔮 Usage Projections
+Daily pace: 67 requests/day (trending up 15%)
+Weekly pace: 1025 requests/week (over limit!)
+⚠️  Estimated depletion: Tomorrow 3:45 PM
+💡 Suggestion: Reduce usage by 25 requests/day to stay within limits
+```
+
+## Benefits
+
+### For Developers
+- **Predictable Planning**: Know your usage patterns and limits
+- **Proactive Management**: Get warnings before hitting limits
+- **Transparency**: Full visibility into policy changes
+- **Business Impact**: Understand how changes affect workflows
+
+### For Teams
+- **Capacity Planning**: Project usage needs and upgrade timing
+- **Cost Management**: Optimize usage patterns
+- **Workflow Continuity**: Prevent unexpected interruptions
+- **Change Management**: Prepare for policy updates
+
+## Impact on Issue #9862
+
+**Before (September 2025)**:
+- Limits decreased from 2000 to 1000 weekly requests ❌
+- No notification to developers ❌
+- Sudden workflow disruption ❌
+- No visibility into usage patterns ❌
+
+**After (with this plugin)**:
+- Immediate policy change alerts ✅
+- Clear usage dashboard ✅
+- Proactive limit warnings ✅
+- Historical change tracking ✅
+
+## Integration Points
+
+The plugin would integrate with:
+- **Anthropic API**: Real usage data and limit information
+- **Notification Services**: Email, Slack, webhook alerts
+- **Analytics**: Usage pattern analysis and trends
+- **CLI/UI**: Dashboard and command integration
+
+## Future Enhancements
+
+1. **Email Notifications**: Direct email alerts for policy changes
+2. **Webhook Integration**: Custom notification endpoints
+3. **Usage Analytics**: Detailed pattern analysis
+4. **Team Dashboards**: Multi-user usage visibility
+5. **API Integration**: Real-time data from Anthropic services
+
+## Contributing
+
+This plugin addresses a critical communication gap that affects developer productivity. Contributions welcome for:
+- Enhanced usage analytics
+- Better projection algorithms
+- Additional notification channels
+- Integration improvements
+
